This invention relates to coincidental locks for preventing theft or unauthorized use of an automotive vehicle, and particularly to a coincidental lock wherein a single key con trolled member may be operated to open the ignition switch and to prevent the use of the gear shift lever to connect the engine with the transmission mechanism.

The objects of the present invention include the provision of a novel coincidental lock referred to which is durable and reliable and can be manufactured at low cost. More particularly, it is an object of the present invention to provide certain improvements conducive to economy and manufacture in the type of coincidental lock shown in the copending application of Carl WV. Blossom and Elmer 0. Peterson, Serial No. 202,210, filed June 29, 1927, and granted on June 19, 1928 as Letters Patent No. 1,674,315.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing, wherein a preferred form of embodiment of the present invention is clearly shown.

Fig. 12 is a modified form of locking bolt.

In the drawing, designates a metal tube which is formed preferably by bending sheet metal into cylindrical form and by holding the abutting ends together by suitable interlocking joint not shown. The tube 20 is closed at one end by a lock barrel or plug 21 attached to the tube 20 by a screw pin 22 and by a locating pin 23 shown in Fig. 8. The other end of the tube 20 receives the cylindrical portion a of a non-conducting terminal block 25 and is provided with oppositely disposed notches 24 for receiving terminal supporting portions 25?) which bear against the portions 26 of the tube 20 which define the ends of the notches 24. A conduit support 27 is received by the tube 20 and bears against the block 25 and is retained in the position shown in Fig. 1 by deforming portions 28 of the tube 20 into a groove 29 provided by the conduit support 27. The end of the tube 20 adjacent the support27 is reinforced by a collar 30 having a flange 31 closely surrounding the support 27 and having certain portions 31a deformed into recesses which are provided in the tube 20 when the portions 28 are deformed into the groove 29 of the support 27.

The block 25 insulatingly supports switch contacts 32 which are secured by terminal bushings 33, each receiving a terminal screw 34. As shown in Fig. 10 each contact 32 is provided with a hole 35 having flats 36 for receiving corresponding flats 37 provided by a portion of the bushing 33 as shown in Figs. 11 and 6. Each plate 32 fits within a recess 38 in the block 25 having parallel sides so that the plate 32 cannot turn while located within the recess 38. The terminal bushing 33 is held in engagement with a plate 32 as shown in Fig. 1 by riveting over a portion of it designated by numeral 39 against a washer 40 located on the outside of the block 25. Therefore the bushing 33 cannot turn when the screw 34 is turned.

The contacts 32 are engageable by a ring contact 41 insulatingly supported by a nonconducting block 42 which is slidable along the short tube 43 connected at one end with a cup-shaped member 44. The member 44 is located within a cam sleeve 45 and is attached thereto by a cross pin 46. The cam sleeve 45 is provided with a helical slot or groove 47 for eceiving a stud 48 attached to the tube 20. Therefore when the sleeve is turned it will move endwise in order to move the member 44 endwise. Motion is transmitted from the member 44 to the contact carrier 42 by a spring 49. Therefore the ring contact 41 will be moved by the turning of-sleeve 45 into engagement with the contacts 32 and the contacts will be maintained in engagement by the pressure of the spring 49.

The cam sleeve 45 is provided with an oblong aperture 50 for receiving a lock cylinder tongue 51 which is attached to a lock cylinder 52 c rrying a plurality of plunger plates or locking bars 53 adapted to move into either of two diametrically opposite longitudinal grooves 54 provided in the lock cylinder barrel 21. When the proper key 55 is inserted 5 in the cylinc er 52 the bars 50 will be withdrawn from the grooves 54 so that their ends will be flush with the cylindrical periphery of the cylinder so that the cylinder may be turned. A set screw 56 which threadedly engages the barrel 21 has a shank 57 adapted to extend adjacent the flange 58 provided bythe cylinder 52. When the screw 56 is located as shown in Fig. 8 the key cylinder 52 cannot be withdrawn from the barrel 21.

It is therefore apparent that when the cylinder 52 is turned by the proper key 55, the sleeve 45will be moved endwise in order to move the contact- 41 into and out of engagementwith the switch contact 32. This endwise movement of the sleeve 45 is used to con- :gear shift lever is used to connect the engine with the. vehicle propeller shaft directly or through a certain gear train. It will be understood that when the gear shift lever is in neutral position, the plates 61 and 62 will be located so that notches 61a and 62a provided respectively by them will be located directly adjacent each other and so as to receive a ball 63 which is guided by an opening 64 in the case 66 and communicating with a bore 65 extending substantially at right angles to the direction of movement of the sliding plates 61 and 62. The bore 65 'slidably supports a locking bolt 66 attached to one endof a Bowden wire 6'? which extends through a Bowden wire tube '68 and also through the'tube 48 which slidabl supports the contact carrier 42. The end of the wire 6? within the tube 20 is formed into a flat coil 69 so that the wire cannot be pulled our from the cup-shaped member 44 and so that the wire 6'? cannot be moved relative to support 27.

the tube 43 but a slight amount since the flat coil 69 is confined between one end of the tube 43 and the cross pin 46. One end of the Bowden wire tube 68 is permanently attached to a shank 70 of a conduit support 71 which is attached to the case 60 by a pin 7 3 extending through a bore in the case 60 and into a groove 72 in the shank 7 O. The end of the Bowden wire tube 68 within the conduit support 71 is flared at 74 against a suitable counterbored recess 7 5 of the shank 70 so that it cannot be withdrawn. The counterbored recess 7 5 also receives a disc 76 through which the wire 67 is slidable, In similar manner, the other end of the tube 68 is attached to the conduit It will be noted that the tube 68 is flare-d at 77 against a counterbored recess in the conduit support 27, said recess receiving a disc '3 8 through which the wire 67 is slidae his. The Bowden wire tube 68 is protected. by an inner cable 80 surrounded by an outer conduit 81-. Each end of the conduit 81 is attached to one of the conduit supports 2'? or 1 in any suitable manner. One manner of securing is by a screw pin 82 extending through the conduit support 71 and another manner of securing is by deforming an end portion 83 of the conduit support 27 into the helical groove provided by the conduit 81.

The construction described and illustrated permits separate assembly of the tube 20, the insulating block 25 carrying the stationary contacts 32-, the conduit support 27, the reinforcing collar 30, the protecting cables 80 and 81, the Bowden wire tube 68 and the cable or conduit support 71. A separate sub-assembly may be made of the parts including the Bowden wire '67, the cam sleeve 45 and parts associated therewith and movable thereby. Another sub-assembly may be made of the lock barrel -21, lock cylinder 52 and tongue 51. The obvious method oft-assembling the sub-assemblies is to insert the free end of the wire 67 through the tube 68 and finally to move the sub-assembly of parts including the cam sleeve 45 and contact carrier 42 within the tube 20. Then the lock assembly is inserted in the tube and the tongue 51 is'connected with the cam sleeve 45. After inserting the wire 67 through the locking bolt 66, its end is bent over at 67a and is clamped against an end wall of recess 67b in the bolt 66 by a clamping set screw threadedly engaging the lock bolt 66.

VV'h'en the key 55 is turned in a clockwise direction as viewed in Fig. 2, the sleeve 45 will be moved endwise toward the left sufficiently to-ca-use the contact 41 to engage the stationary contacts 32 and to cause the looking bolt 66 to move toward the rightas viewed in Fig. 1 in order to release the ball 63. Under these conditions the ignition circuit will be closed to permit operation of the engine and the driver may then operate the gear shift lever to connect the engine with 'right as viewed in Fig. 1, in order to disengage the contacts 41 from the contact 32 and to move the bolt 66 toward the left as viewed in Fig. 1 in locking engagement with the ball 63.

Fig. 12 shows diagrammatically a device for locking a transmission gear shift having shittable rods 100 and 101 provided with notches 102 and 103 for receiving locking bolts 104 and 105 respectively. Each bolt has i a central hole and central threaded recess.

The bolts are operated by a single wire or rod 106 and are operatively connected by a wire 107. These wires and bolts are assembled in the following novel manner: The

wire 107 is passed through the bolt 105 and the end to be attached to the bolt 105 is bent at 107 a. The end 107a is clamped to the bolt 105 by a set screw 108. A screw 109 having a central hole is passed over the wire 107 and the end to be fastened to the bolt 10 1 is bent at 107?). The wire 106 is passed through the bolt 104 and is bent at 106a. Then the wire end 107?) is passed into the threaded recess in the bolt 104 and is turned out of alignment with the wire end 106a. Both wire ends 106a and 1075 are clamped to the bolt 10% by the screw 109, using a screw driver having a split blade which straddles the wire 107.
